APPARATUS FOR CONDENSING ELECTRICITY.

SPECIFICATION forming part of Letters Patent No. 792,443, dated June 13, 1905. Application filed December 2, 1904. Serial No. 235,196.

To @ZZ 71171/0717, it mf/,7j concern/ Be it known that I, JosErH Monwrrz, a citi- Zen of the United States, residing' inthe city and county ot Philadelphia, State ot' Pennsylvania, have invented a new and useful Apparatus At'or Condon sing Electricity, of which the following is a speciiication.

The object of my invention is to produce a condenser which shall operate both to store electrical energ'y and to increase the intensity otl the charg'e.

A further object of my invention is to bind successive inclosed charges ot' electricity of greater density by an initial charge of relatively lower density.

In the drawings, Figure l represents a perspective view of one form or' my invention. Fig. 2 represents a vertical cross-section through the center of Fig'. l.

Similar numerals of reference indicate corresponding parts in the figures.

Referring' to the drawings, l designates the outer shell or support ot' my condenser, here shown and preferably of cylindrical shape, most desirabl y constructed of paper permeated with resin or parallin or coated with lacquer'. It may, however, be ot' g'lass, ebonitc, mica, or other dielectric. lVithi n this wall are placed successive and inclosed or partly-inclosed shells, here shown as but two in numbernamely, 2 and These walls are supported upon any suitable non-conducting' base 4 lor convenience. For purpose of illustration the walls are here shown as spaced considerably and corresponding'ly few in number; but it will be evident that they may be placed quite close together and the number increased indelinitely, it' desired.

Upon the outer and inner cylindrical t'aces l, 2, and 3 are placed successive coatings, as ot' tin-foil or other thin metal, constituting, respectively, coverings 5, '7, and 9 and linings 6, S, and IO. The outer covering' 5 is connected with a source of electricity by a terminal ll, and the inner lining' l() is connected by a suitable terminal l2 with the earth or the opposite pole ot' said source of electricity.

In operation the charge of electricity, preferably from a frictional machine, Ruhmkortt coil, or another condenser, is communicated to the outer coating while the inner coating is connected, preferably, to the ground, so that the outer coating' 5 induces a charge ot opposite kind upon the enjoining lining' 6, which in turn induces a charge ot' like character to the initial charg'e upon coating' 7, and so on, the tinal charge induced upon the inner lining' IO being' drawn from the earth and being' opposite in character to the initial supply. It will be evident that each induced charge will be a quantity corresponding' to the initial charge, but will be distributed upon successively a smaller area than that ot' the initial charge, with the result that the density of charg'e will be increased successively, the charge reaching its highest concentration upon the innermost lining'.

It will be evident that various changes may be made by those skilled in the art which may come within the scope ot my invention, and I do not, therefore, desire to be limited in every instance to thc exact construction herein shown and described.

Having thus described my invention, what I claim as new, and desire to secure by [Letters Patent, is-

1. In a condenser, an outer coating' and a plurality ot' successively-inclosed cylindrical dielectrics and coatings.

2. In a condenser, a plurality of concentric continuous supports, arranged one within another, and coatings thereon.

3. In a condenser, a plurality ot' disconnected concentric continuous coatings adapted to hold charges ot alternate character.

4. In a condenser, a plurality of dielectric supports and a plurality of inductively-arranged metallic coatings ot' different size upon each support.
